php ( variable leacture-7)

what's up everybody this is quivered taking and this we're going to learn

about beach the sessions what our peach piece sessions well it's a way to

information across multiple pages and in phd to this information in sessions

is stored inside variable named on their score session it's a global

variable so by cookies where the information has stored on the users

computer and and text file sessions in sessions that information is stored

inside a global variable(Dallas Website Development) so i for their here named sessions and i'm going to

create a new file and i'm going to name it one that ph the way we start

session and b c use using a function sessions right at this point the global

variable on the core session becomes available so we can now set our session

valley is so we can today for example and you can treat this session you can

think of the session global era global variable has an era so we can said

the new named gene called username and said into a value and also set of

some other one [COUGH] what i'm going to do here in named role and at this

point let me just use my function to print out the iran and a better way and

i'm going to say pre are session to print out the rate and i'm going to open

it and as you can see the being variable rate has been printed out and

everything is working is expected now we can also say on this which session

variables had been set because the be hard to go and so on this page we're

setting our session variables now in order for us to check at the session is

working on other pages i'm going to create an a page and the gang came into

and i knew that each and i'm going to create html link i think into that

page the that with two of the game and on this page want every page you have

to their you're going to be access in your session variables and you also

have to use the function stations starred otherwise you're not going to have

access to that global session variable and at this and the information is

going to be available to us on this page as well so contest that out by

printing out there session or a and i'm going to go ahead and run one the

page me now which is the first page where we're setting that sessions

variables section very well have been set and if i got to to that pc as you

can see that session keys and values are still available because well what

we have successfully set the session and now we're access in them on the

second page so that how sessions work and that's a simple is that now we can

also modify session variables for example i can save session his name

because these a reality i can say said antinori username and then we can

print recession again that's what happens and i'm going to go ahead and 

 

open up one that they speak with on the link and now the you can see our original

values as well as the new valley so that's how you might have fire session

variables easy and let's see here lastly if you want to and the session you

use a function called session this underscore destroyed at this point our

social bees troy so if i around this file we need to that says can see this

session keys are not available in a more because we have destroyed [SMACK]

and and if i go back to one which is where we are setting our session

variables and then got a page too then all of our tease valleys have become

available(Dallas Website Development) so by using session destroy you're destroyed the session and raise

the session the re as well so that's how sessions work if you guys found

this useful please like sharon saw scribe and i'll see next time clever
